[PULL 5/6] configure: Only decompress EDK2 blobs for X86/ARM targets

[Thomas Huth <thuth@redhat.com>]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

The EDK2 firmware blobs only target the X86/ARM architectures.
Define the DECOMPRESS_EDK2_BLOBS variable and only decompress
the blobs when the variable exists.
